This invention relates to a computing travel chart.

The object of this invention is to provide a combination chart and computing board on which the progress of an airplane flight may be indicated and followed, or observed, both as to time and location in its progress from one terminal to the other in its flight.

Another object of this invention is to provide an indicating and computing board of the foregoing character in which provision may be made for the geographical changes in time, so the clock time may be progressively indicated on the chart as the flight progresses.

Another object of this invention is to provide an indicating and computing panel board of the character described above, in which the time may be variably indicated corresponding to the geographical location of various geographical points, such as the major cities over which or through which an airplane flight may pass.

The construction of a preferred embodiment of the invention is shown in the accompanying drawings, in which:

Fig. l is a front View in perspective elevation, with parts broken away to show certain details of construction of the card supporting frames, representing selected cities and the numbered hours of a time interval somewhat in excess of one day;

Fig. 2 is a vertical section looking endwise along the line 2-2 in Fig. 1;

Fig. 3 is a horizontal section of a portion of the frame in Fig. 1 taken along the line 3-3 in Fig. 1.

As shown in the drawing, the indicating and computing device It comprises an indicating back board II, a pair of stationary card holding frames I2 and I3, one or more intermediate card holding frames I4 and I5, and a box frame for enclosing the card holding frames and the chart, comprising a base [6 and a cover closure frame I1 fitting snugly over the rim flange is on the base I6.

The indicating panel or back board II is rectangular in shape, of any suitable lightweight material, such as wood, and is marked or ruled with a series of parallel horizontal lines 2[ that are equally spaced vertically and that extend horizontally from near one edge of the indicating panel II to the opposite right hand edge of that panel.

The two card holding frames i2 and I3 are fixedly secured to the base panel Ii near the top and bottom ends by simple suitable means such as the screws 22, so the frames I2 and I3 will be substantially vertical, parallel to the two vertical side edges of the indicating base I I, and perpendicular to the horizontal ruled lines 2I on the indicating base panel 1!. Those two frames I2 and I3 serve as holders for adjustably movable time indicating cards 23 which may be vertically shifted and adjusted to selected positions to dispose the clock indicating numbers on the card 23 adjacent the respective horizontal lines 2| which are thus to be identified and designated the corresponding clock hour at the corresponding geographical location, as indicated by the identifying card 24.

provide a narrow channel for the turned flanges 26 and 27.

holding frame I3, in fixed position. In order to hold the hour-indicating card 23 in selected adjusted position, the frames i2 and I3 are provided with similar inwardly turned flanges 28 and 29 that provided suificient holding friction against the cards 23 to hold the card against casual displacement after it has been moved to a selected and adjusted position in the card hold ing frames l2 or I3.

The distance between the card holders !2 and I3 is subdivided percentage-wise by a scale 3I along or near the lower edge of the indicator base II. As indicated in Fig. 1, the distance between the two frames l2 and I3 is divided by the scale 3| from zero to 100 percent.

As identified by the markers in the card holders 25 of the two card holding frames 52 and !3, those two frames may be marked to identify the terminal points of an airplane flight, and for the purpose of illustration, those two points are shown as New York and Los Angeles. In order to indicate the flight, assuming, for example, a non-stop flight, a line 32 may be drawn by meansof a piece of chalk 33 or other easily erasable material between the card holders I2 and I3, be-- tween the terminals of the horizontal lines indicating respectively the hour of departure and the projected hour of arrival.

In order to check the schedule of flight against actual flying time and conditions, or to check geographical locations against the projected time of the flying schedule, the intermediate card holders I4 and I5 may be suitably positioned at appropriate spaces between the two terminal frames I2 and I3 to correspond to the flying geographical distances of the considered points relative to the terminal geographical 10- The card 24 is held in an. appropriately shaped card holder 25, formed to top and bot-- tom edges of the card 24 and having inwardly- The card holder 25' is suitably mounted and attached to the card cation, shown herein by way of example as the cities Denver and Chicago.

The two intermediate movable frames l4 and I5 are provided with pointers 35 at their lower ends, with sharpened front edges, to permit the frames l4 and IE to be suitably disposed along the bottom percentage scale 3E.

The side edges of the movable frames I4 and I5 are similar to theside edges 28 and 2s shown on the stationary frames l2 and E3, in order similarly to hold time indicating cards 23 at appropriate levels to line up the hour numbers proper- 1y at the corresponding horizontal lines; 2] al-r ready previously identified by the hour numbers at the terminal point, shown as New: York, for: example, making proper allowance for the changein the time at the city represented by the-designating card 24 for the associated frame 14 and'l5.

In order to hold the indicating base board. ll.

and the movable card holder frames I l and [5 in assembled position, the baseboard; H' and the frames are enclosed in a box frame consistin of the back 16 and the border frame. ll. Asshown in more detail in Fig. 2, the back It is provided with the peripheral upstanding flange I8 which serves as a friction border to receive and hold the front closure frame ll, thereby serving as a closed box to hold the base N and the card frames It and 15, in assembled position; while at the same time providing suff cientspace between the front surface of the base H- and'the juxtaposed back surf-ace I l-a of the closure-frame I! to provide a channel space along thetop and bottom edges ofthe closure frame l 'l toer-mit' free horizontal sliding movement of; the two frames l4 and l5 along-the indicator, base ll; As shown in more detail in Fig. 2; the top and bottom borders of the movable frames Hi'and l5 are of appropriate-thickness to substantially fill the space between thefront, or top, surface of the I J:

indicator base H and the rearv surface !l'a-.of-= the closure or border frameii.

In order to provide for lightnessin weight, theseveral components of the computing device may be made of light weight material, such as Wood or plastic, and the cover frame El particularly should be made of plastic in orderqto expose the I figures of the scale 3! along the lower edge of the indicator base II.

The travel courses may be drawn toshow the' origin and'destination of flight, with stop-.overs' wherever they occur. Thus, thebroken line-32% may represent a flight from-New York to. Los Angeles, or one leg of a flight from somepoint in Europe to Hawaii, for example, with stop-overs at New York and Los Angeles. An example ofa. flight in the reverse direction, with an intermedi' ate stop-over is indicated by the broken line While the invention has been illustrated'in a preferred form of construction, it is to be understood that various changes or modifications may be made in those details of construction without departing from the spirit and scope of the invention as set forth in the appended. claims;
